Perhaps you should try some spelling variations:
present » presenta, presentan
presente » presentae, presentane
presentana » presentaana, presentanana, presentan, presenta, presentar
presentea » presentaea, presentanea, presenta, presentan, presencia
presencian » presencia, presentan, prevencion
detection » deteccion

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "1965 Philippine ((present OR (presente OR presencian)) OR (presentana OR presentea)) detection~".
• Adding a wildcard symbol may retrieve word variants: 1965 Philippine ((present OR (presente OR presencian)) OR (presentana OR presentea)) detection*.
